MACHINE FOR ROLLING HOOPS.

SPECIFICATION forming part of Letters Patent No. 324,973, dated August 25, 1885.

Application filed July 21, 1884.

T aZZ whom it may concern:

Be it known that we, GEORGE G. ANNABLE and HENRY W. LEONARD, of Syracuse, in the county of Onondaga and State of New York,

have invented new and useful Improvements in Machines for Rolling Hoops, of which the following is a specification.

This invention relates to a machine for rolling sheet-metal hoops designed to be applied to the lower edges of paper pails for the purpose of binding and stiffening the same. In order to properly prepare these hoops for attachment to the inner side of that portion of the pail which extends below the bottom, it is necessary to give the hoop a tapering form corresponding with the taper of the side of the pail.

Our invention has the object to produce a machine whereby such hoops can be pro duced rapidly and uniformly; and it consists in the improvements in the construction of the machine, which will be hereinafter fully described, and pointed out in the claims.

In the accompanying drawings, consisting of two sheets, Figure 1 is a longitudinal sectional elevation of our improved machine. Fig. 2 is a horizontal section in line 00 {I}, Fig. 1. Fig. 3 is a front elevation of the machine. Fig; 4: is a sectional elevation of the shapingrollers on an enlarged scale. Fig. 5 is afragmentary perspective view of the hoop-blank. Fig. 6 is a similar view of a finished hoop i11- vcrted. Fig. 7 is a vertical section of the lower portion of a pail with the hoop applied thereto.

Like letters of reference dcnotelike parts in the several figures.

A represents the base-plate of the stationary frame of the machine provided with standards A A A.

B represents the lower shaping-roller, secured to a horizontal shaft, 6, which is supported in bearings b I), attached to the lower portions of the standards A A 5 c is a horizontal setscrew bearing against the rear end of the shaft 1) for adjusting the latter horizontally.

D is a gear-wheel secured to the shaft 1) between the standards .A A, and d is a pinion meshing with the gear-wheel D and mounted on the driving-shaft d. The latter is set in (No model.)

motion by an endless belt and pulleys, E E, or other suitable means, and is journaled in suitable bearings, c c.

F represents the upper shaping-roller, se cured to the lower end of an inclined shaft,f, which latter is journaled in adjustable bearings g g. The upper portions of the stand ards A A are bifurcated, each being co1nposed of two curved parallel bars or arms, hh and t 13, respectively. These arms or bars are curved concentric with the point at which the axes of the rollershafts b and f intersect. The bearings g g are fitted to slide between the arms h it and i 2', respectively, and provided wit-h flanges overlapping the front and rear sides of these arms, as represented in Fig. 2, whereby the bearings are retained on the arms. The lower bearing, g, is provided with a sctscrew, Z, which passes through a cappiece, L, secured to the upper ends of the arms h h and t t, and serves to adjust the bearing 9 toward the roller B. The upper bearing, 9, is provided with a screw, m, which extends through the cap piece L, and is provided on both sides of the latter with screw-nuts m 112?, whereby the bearing 9 is secured in any de sired position. By raising orlowering the up per bearing, g, the angle of the shaftf with the shaftb and theposition of the upper roller, c F, are regulated, as may be required.

N N are bevel gear-wheels, which are secured, respectively, to the shafts Z) and f, and whereby motion is transmitted from the shaft b to the shaft f. 8

The lower shaping'roller, B, is constructed with a concave annular face, a, terminating at its outer edge in an annular tongue, at, and at its inner end in a conical face, a". The upper shapingroller, F, is constructed with a con- 9 vex annular face, 0, terminating at its inner edge in an annular groove, 0, and at its outer edge in a conical face, 0". The tongue at fits into the groove 0, the concave face or against the convex face 0, and the conical face a against the conical face 0 The concave face a and the convex face 0 are inclined with reference to the axes of the rollers, so as to give the hoop-body a taper corresponding with the taper of the lower end of the pail, and this inclination is made approximately coincident with the curvature of the inner side of the lower end of the pail, so that the point at which the axes of the shafts b and f intersect coincides with the center of the pail-bottom, and the faces a 0 with the inner periphery thereof, as indicated by dotted lines in Fig. 4.

P represents a horizontal table arranged below the rollers B F. Q is a straight guide, and Q a curved guide, secured to the table 1? respectively on opposite sides of the rollers B F, and serving to guide the hoop-blanks between the rollers and the rolled hoop from the rollers.

The guides Q and Q are secured to the table P by screws q, passing through slotted lugs q, whereby the guides are rendered adj ustable on the table.

The hoop-blanks are straight strips of sheet metal, prepared for rolling by bending over one edge of the strip in a suitable bendingtool, as represented in Fig. 5. These blanks are placed on the guide Q, with the bent portion resting 011 the upper edge of the guide, and fed between the rollers. The latter seize the blanks and rapidly roll them to the desired form. The faces a 0 give the taper to the body of the blank, the tongue 11. and groove 0 bend the wide flange 1", which overlaps and embraces the lower edges of the pail, and the faces a 0 turn the narrow flange T, which fits against the under side of the bottom of the pail and supports the bottom, as represented in Fig. 7. In this manner the straight blanks are rolled into hoops of the desired tapering form rapidly and economically.

By adjusting the bearings g g of the upper roller, F, the latter is adjusted with reference to the lower roller, B, and by adjusting the set-screw c the lower roller, B, is adjusted with reference to the upper roller, F. As the guides h h i t, on which the bearings g g are adjusted, are concentric with the center of the roller-faces by which the hoop is formed, the upper roller, F, moves concentrically with this point when these bearings are adjusted.

We claim as our invention 1. The combination, with a shaping-roller, B, having a concave face, a, and an annular tongue, n, of a shaping-roller, F, having a convex face, 0, and an annular groove, 0, whereby a flanged tapering hoop is produced, substantially as set forth.

2. The combination, with the shaping-roller B, having a concave face, a, annular tongue n,

and conical face M, of a shaping-roller, F, having a convex face, 0, annular groove 0, and conical face 0 substantially as set forth.

3. The combination, with the roller B, constructed with an annular tongue, 42, and secured to a shaft, 72, of the roller F, constructed with an annular groove, 0, and secured to a shaft, f, arranged at an angle to the shaft Z), and means whereby said shafts are geared together, substantially as set forth.

4.. The combination, with the roller B, con-- structed with an annular tongue, 71., and se cured to a shaft, 1), of the roller F, constructed with an annular groove, 0, and secured to a shaft, f, arranged at an angle to the shaft 1), and a guide, Q, whereby the blanks are conducted between the rollers, substantially as set f0rth..

5. The combination, with the roller B, constructed with an annular tongue, a, and secured to a shaft, b, of the roller F, constructed with an annular groove, 0', and secured to a shaft, f, arranged at an angle to the shaft 1), and a curved guide, Q, which receives the rolled hoops from the rollers, substantially as set forth.

6. The combination, with the shaft b and roller B, secured thereto, of a supportingframe provided with concentric guides, ashaft, f, carrying a roller, F, and bearings g g, supporting the shaft f, and made adjustable in the concentric guides of the frame, substantially as set forth.

7. The combination, with the shaft b and roller B, secured thereto, of the shaft f, carrying a roller, F, means whereby the shaft f is made radially adjustable, and gear-wheels conv necting the shafts b and f, substantially as set forth.

8. The combination, with the shaft 1) and roller B, secured thereto, of the shaft f. carrying a roller, F, means whereby the shaft f is made radially adjustable, gear-wheels connecting the shafts b and f, and means whereby the shaft b is made lengthwise adjustable, substantially as set forth.
